HDCP 2.2

HDCP 2.2 is High Defenition copyright protection. This creates a secure connection at both ends of the cable. HDCP makes sure that the data within the cable (HDMI or Display Port) is secure. If your device does not support HDCP2.2 this cannot be rectified by a firmware upgrade as this requires an actual chip.

High-resolution audio files usually use a sampling frequency (Sampling frequency means the number of times samples are taken per second when the analogue sound waves are converted into digital) of 96kHz or 192kHz at 24-bit, but there are many other frequencies which can be used.

4K UHD is a display which has 3840 x 2160 pixels (8.3 megapixels). This is 4 times as many pixels as we had with HD

The industry standard for 4K is 4096 x 2160 (at a 19:10 or 1.9:1 aspect ratio)

4K images and video content are 8.3 megapixels in size per frame so will require a fast media delivery mechanism.

In order to cut down on the size of the transmitions, compression and de-compression is used (called CODECS) to deliver and rebuild the images. HEVC and VP9 are two such CODECS. You will need approx 25mB/s to receive these type of transmissions.

Digital Video Recorder

I use DVBviewer as my Media Centre. This app has never let me down. It works with Windows10.

HDMI 2.0 can use up to 8 channels of uncompressed audio at sample sizes of 16-bit, 20-bit and 24-bit, with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz.

HDMI 2.0b is capable of using High Dynamic Range (HDR) video

Bandwidth up to 18Gbps 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution

Can use up to 32 audio channels for an audio setup.

1536kHz audio sample frequency for the highest audio quality.

Dual video streams to multiple users on the same screen

Simultaneous delivery of multi-stream audio to 4 listeners.

Support for the wide angle 21:9 video aspect ratio

Dynamic synchronization of video and audio streams

CEC extensions can provide more expanded command and control of consumer electronics devices through a single control point

HDMI 2.0b does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth.
